Carry-on details
Allowed. Over-the-counter nasal sprays (like saline rinses, Afrin, or Flonase) are treated as a standard liquid — a travel-size bottle of 3.4 oz (100 mL) or less fits in your quart-size liquids bag along with your other liquids. Prescription nasal medication is treated as a medically necessary liquid and is exempt from the 3.4 oz limit and the quart bag — you can bring a larger, reasonable-for-your-trip quantity as long as you declare it to a TSA officer at the checkpoint.
Checked-bag details
Allowed. No restriction on nasal spray, OTC or prescription, in checked baggage.
Quantity limit
3.4 oz (per container)
Special instructions
If your nasal spray is prescription or medically necessary, keep it separate from your quart-size bag and tell the TSA officer you're carrying it so it can be screened on its own.

FAQ
- Does nasal spray count toward my quart-size liquids bag?
- A regular over-the-counter bottle does, but it's almost always small enough to fit easily. Prescription nasal spray is exempt from the 3.4 oz rule if you declare it at the checkpoint.
- Can I bring more than one bottle of nasal spray?
- Yes, as long as each over-the-counter bottle is 3.4 oz or less and all your liquids fit in one quart-size bag. Prescription nasal spray can exceed that limit if declared.
